Struct Message 

pub struct Message {
    pub role: Role,
    pub content: String,
    pub name: Option<String>,
    pub tool_call_id: Option<String>,
    pub tool_calls: Option<Vec<ToolCall>>,
}

A message in a conversation.

Fields

role: Role

Role of the message sender

content: String

Content of the message

name: Option<String>

Optional name (for multi-user conversations or tool calls)

tool_call_id: Option<String>

Tool call ID (for tool role messages)

tool_calls: Option<Vec<ToolCall>>

Tool calls emitted by the assistant.

Implementations

impl Message

pub fn user(content: impl Into<String>) -> Self

Create a user message.

Example

use simple_agent_type::message::{Message, Role};

let msg = Message::user("Hello!");
assert_eq!(msg.role, Role::User);
assert_eq!(msg.content, "Hello!");

pub fn assistant(content: impl Into<String>) -> Self

Create an assistant message.

Example

use simple_agent_type::message::{Message, Role};

let msg = Message::assistant("Hi there!");
assert_eq!(msg.role, Role::Assistant);

pub fn system(content: impl Into<String>) -> Self

Create a system message.

Example

use simple_agent_type::message::{Message, Role};

let msg = Message::system("You are a helpful assistant.");
assert_eq!(msg.role, Role::System);

pub fn tool(content: impl Into<String>, tool_call_id: impl Into<String>) -> Self

Create a tool message.

Example

use simple_agent_type::message::{Message, Role};

let msg = Message::tool("result", "call_123");
assert_eq!(msg.role, Role::Tool);
assert_eq!(msg.tool_call_id, Some("call_123".to_string()));

pub fn with_name(self, name: impl Into<String>) -> Self

Set the name field (builder pattern).

Example

use simple_agent_type::message::Message;

let msg = Message::user("Hello").with_name("Alice");
assert_eq!(msg.name, Some("Alice".to_string()));

pub fn with_tool_calls(self, tool_calls: Vec<ToolCall>) -> Self

Set tool calls for assistant messages.

Trait Implementations

impl Clone for Message

fn clone(&self) -> Message

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Message

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Message

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Message

fn eq(&self, other: &Message) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Message

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
